This portable device was used to
collect data, mostly from barcodes, in warehouses. It has IR
port for communicating with PC and barcode scanner.
Using data collectors changed warehouse management - employees
could just walk in warehouse and scan incoming goods, then dump
data to PC. By scanning outcoming goods it was possible to
automate warehouse management.

Unfortunately I don't
have much information about this device. Japanese manufacturer
made only hardware with base OS, then systems seller installed
their own software, In my unit systems seller is ICS, from
Germany, and software is "Easy pack 4.0". This unit is quite
old, so even ICS has no information about it in their web site.

To power device up, use 5V (or 6V, not recommended) DC power
supply and connect it to battery charging terminals:
